PACKING- WASHER.

Application led May 10, 1922. Serial No. 559,736.

To all whom t may conce-m.'

Be it known that HARRY B'. KIMMEL, a citizen of the United States,residing at Highland Park, in the county of Wayne and State of Michigan,has invented certain new and useful Improvements in Packing l/Vashers,of which the following fication. i

This invention relates to packing members for pipe joints, and has forits object packing members which will take the place of ordinary`packing washers and affords a more reliable packing because it is notpossible to unseat the packing the way ordinary washers unseat.

I have particularly in mind the joint where a water meter is set in awater line or the joint in a water closet tank pipe. The water pipe isordinarily provided with a flange and leather washer which is jammedagainst the end of the intake pipe of the tank. In course of'time veryoften this washer is squeezed out and consequently ceases to act as apacking. The special washer which I have designed cannot be squeezed outand forms a cheap and re;- liable packing member at this point.

In the drawings:

Fig. l is a vertical cross section of a water pipe and awater closettank intake pipe and the joint intervening between them.

Fig. 2 is a composite section and elevation of the packing member.

(i designates the water pipe provided with the usual flange 7) oppositethe end of the watervcloset pipe c; nl designates the usual nut adaptedto force the. two pipe ends together against' the intervening leatherwasher.

. In place ot' the usual washer I use a paeking member made of `a softmetal fibre or similar material which will easilyllow under heavypressure, such as lead; this member is provided with the usual washerflange e and is formed with a body having a pair ofcone frnstrums f and(7, arranged with abutting bases. The washer flange c adjoins the bodyof the packing member at the line of junction between the two conefrustrum bases. Preferably the washer flange initially tapers from itsinside to its outside, as shown in Fig. 2.

Beads h and z' are formed on the packing is a speciy member on theoutside thereof at the bases of the cone frustrums immediately7adjoining the washer flange. These beads perform a very important officein the sealing of the joints. y They afford surplus soft metal toencounter the inside corners of the pipe ends. The sharp corners dlgdirectly into this bead and cause the soft metal to flow to each side ofthe corner where it is ammed in between the body of the packing memberand the pipe ends. The washer flange being thicker on the outside thanthe inside permits a flowing of the soft metal to ell'eetually seal thejoint at the outside corners of the joint ends. This forms a very goodseal.

The double cone frustrums form a body of sufficient resistance topreclude the pressure forcing the pipe ends together` causing the washerflange to disengage from its seat. In fact, the design of the washerflange being of greater thickness on the outside than on the inside andthe beads serving in imbedding the pipe corners into the soft materialof the packing member prevent the washer working toward the inside ofthe pipes under the pressure.

What I claim is:

l. A packing washer comprising a body portion having a hollow interiorand .open at both ends, and a laterally extending flange integraltherewith and positioned intermediate of the ends of the said bodyportion, and beads extending around said body portion at the unionbetween the flange and the body portion, composed of distortable andeasy-flowing material whereby the material of said-bead is caused toflow into the flange when pressure is applied thereto.

2. In a packing washer, comprising an open end hollow body portionprovided with a. laterally extending flange integral therewith. saidflange thicker on the outside than onthe inside and beads composed ofdistortab'le and easy-flowing material positioned at the union of theflange and body portion whereby the material of the bead is caused toflow into the flnage when pressure is applied thereto for the purpose ofproviding material for thickening the in side portion of the flange.

In testimony whereof I aflix my signature.
